DRAG.

Specification of Letters Patent.

Patented Feb. 26, 1907.

Application filed July 12, 1906. Serial No- 325,969.

To aZZ whom it may concern.-

Be it known that I, FRANK DARLING, a citizen of the United States, residing at Morris, in the county of Grundy and State of Illinois, have invented a new and useful Drag, of which the following is a specification.

This invention relates to drag-bars; and its object is to provide a device of this character which can be readily connected to a plow or pulverizer and will throughly pulverize the soil immerhately after it has been upturned by the plow.

Another object is to provide a drag-bar made up of sections and carrying a toothed head which is movable, so as to ride smoothly over uneven surfaces.

A still further object is to provide means for raising or lOWOIlIlg the drag-bar and for hold.ng it in raised position when it is desired to support the same out of contact with the ground.

With the above and other objects in view the invention consists of supporting-bars adapted to be secured to the plow-frame in any desired manner, and carried by the bars is a clamping head, to which is adjustably connected a hanger having an arm p.votally connected thereto. This arm is adjustably secured to the central portion of a sectional bar in which teeth are detachably secured. A tension device connects one portion of the hanger with the arm, so as to hold the teeth normally pressed against the ground. Means are provided whereby the toothed bar may be swung upward out of contact with the round and securely locked.

T e invention also consists of certain other novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointedout in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings, Figure 1 is a plan view showing two drags connected to the supporting-bars. Fig. 2 is a side elevation of one of the drags. Fig. 3 is a similar view showing the opposite side thereof, and Figs. 4 and 5 are detail views of the teeth of the drag.

Referring to the figures by characters of reference, 1 1 are parallel bars adapted to be fastened to the frame of a plow in any suitable manner, and on these bars are disposed one or more drag-bar attachments, and as all of the attachments are of the same construction and arrangement a description of one will suffice for all. A clamping-head 2 is disposed beneath the bars 1 and has two concavities 3, in which the bars are seated. The bars are clamped within these concavities by means of a recessed cap 4, which is fastened to the head by means of a bolt 5, extending through the center thereof. A curved plate 6 extends laterally from and is integral with the head 2 and has a series of openings 7 disposed in an arc concentric with the bolt 5. A bracket 8 is secured upon the plate 6 by means of a bolt 9, extending from one of the openings 7, and a lever 10 is pivoted upon this bracket. A locking-dog 11 of any preferred construction is mounted on the lever and is adapted to ride upon the upper curved edge of a standard 12, secured on the plate 6, and'having a stop-lug 13 at one end of said curved edge and a notch 14 adjacent the lug. A hanger 15 is disposed beneath the head 2 and plate 6 and has a lateral extension 17, one end of which is secured to the head by means of bolt 5, while the other end is fastened to the plate 6 by the bolt 9, which bolt also serves to fasten the standard 12 in position. An arm 18 extends from the lower edge of the hanger 15 and is slotted longitudinally, as shown at 19. A bolt 20 is mounted in this slot and serves to clamp the end of an angular guide-arm 21 in position. This arm is arranged parallel with the arm 18 and constitutes a guide and keeper for an arm 22, which is pivoted on a bolt 23, secured to the lower end of the hanger 15. The upper end of this pivoted arm is adapted to swing between the arms 18 and 21, and the bolt 23 is adapted to be placed within any one of a series of apertures 24 in the arm 22 so that said arm can be adjusted longitudinally.

An eye 25 is formed at the lower end of the slotted arm 18 and receives a bolt 26, formed at one end of a coiled spring 27, said bolt being provided with a nut 28, whereby the same can be adjusted and locked. The other end of the spring 27 engages a hook 29, extending from the lower edge of the arm 22. A curved arm 30 extends from the upper edge of the pivoted arm 22 and has a series of openings 31 arranged in an arc concentric with a pivot-bolt 35, extending through the lower end of arm 22. This bolt is mounted within a fork 33, extending upward from the central portion of one member 34 of a sec tional tooth-bar. Another bolt 32 extends through the end of the fork and is adapted to be placed within any one of the openings 31, so as to lock the arm 22 at a desired angle to the fork. Said bolt also engages a link or rod 36, which is pivotally connected to the lever 10.

The member 34 of the tooth-bar has a series of parallel grooves 37 in one face, and concavities 38 are preferably formed between these grooves, so as to reduce the quantity of metal necessary in forming the member. Another member 39 is used in connection with the member 34 to complete the tooth-bar, and this member is similar to the member 34, in that it is formed with parallel grooves 40, adapted to register with the grooves 37. Ali ning openings 41 are formed in the two members for the reception of bolts 42, whereby the members may be drawn together. In each set of grooves 37 and 40 is disposed the shank 43 of a tooth. Iwo forms of teeth are preferably employedto wit, straight teeth '44 and angular teeth 45-the two forms being disposed alternately, as shown. Shanks 43 are of less width than the teeth, and therefore shoulders 46 are formed at the lower ends of the shank and are adapted to abut against the member 34 of the tooth-bar. Lugs 47 are disposed at the upper ends of the shank and are adapted to overlap the upper edge of said member 34. It is therefore obvious that when the shanks are placed within the grooves and the members 34 and 39 are drawn together. said shanks will be clamped in position with the shoulders 46 and the lugs 47 overlapping opposite edges of themember 34, and the teeth are thus held against displacement. By loosening the two members 34 and 39 any one or more of the teeth can be quickly detached and new ones substituted.

It will be understood that when the lever 10 is unlocked from the standard 12 the spring 27 will pull the lower end of the arm against the ground. Of course should the teeth strike any unresisting obstruction, such as a large stone or a stump, they would swing upward thereover and tension the spring. By removing the bolt 9 the hanger 15, standard 12, and bracket 8 can be moved to a desired position onthe plate so as to hold the toothed head at a desired angle in relation to the direction of travel of the plow. By swinging the lever 10 upon its fulcrum the tooth-bar will be swung upward, the bolt 23 serving as a pivot therefor, and the dog 11 will engage the notch 14 to lock the parts in raised position. The guide-arm 21 serves to prevent arm 22 from twisting or becoming displaced while the teeth are moving over an uneven surface. By arranging a series of drag-bars such as herein described upon the bars 1 a large area of soil may be quickly pulverized, and as each drag-bar is mounted independently of the other all of said bars are capable of independent movement and will therefore adapt themselves to any curvature or unevenness of the ground. By adjusting the nut 28 on bolt 26 the tension of the spring 27 can be increased or diminished, so as to regulate the pressure of the teeth upon the ground.

The preferred form of the invention has been set forth in the foregoing description; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to makes such changes as fairly fall within the scope of the claims.

What is claimed is 1. A drag comprising a support, a head secured thereto, a tooth-bar connected to the head, means for exerting a constant downward pull upon the tooth-bar, and means for raising the tooth bar against the action. of said pulling means.

3. In a drag the combination with a support; of a head secured thereon, a tooth-bar, an adjustable connection between said bar and the head, means for exerting a constant downward pressure upon the bar, means upon the head for raising the bar, and means for locking said bar in raised position.

4. In a drag the combination with a support; of a head secured thereto, a hanger adjustably connected to the head, a tooth-bar,

an arm adjustably connected to said bar and pivoted to the hanger, and means connected to the hanger for exerting a constant downward pressure upon the tooth-bar.
